Abstract

The invention belongs to the technical field of ocean development and ocean protection, and relates to an underwater caisson oil leakage detection device which comprises a plurality of water inlet pipes, a water outlet pipe, an oil collecting cover, a detection unit and an oil discharge hole. The plurality of water inlet pipes are connected with one end of the water outlet pipe, the detection unit is arranged in the oil collecting cover and connected with the other end of the water outlet pipe, the top of any side wall of the oil collecting cover is provided with an oil discharge hole, the water inlet pipes suck liquid to be detected, the liquid to be detected enters the detection unit through the water outlet pipe for detection, and the detected liquid flows into the oil collecting cover. And the oil is discharged from the oil discharge hole. The detection unit body is used for performing fixed-point detection on fluid flowing through the oil discharge hole and feeding back the oil leakage condition in time; in this way, oil leakage detection and monitoring can be conducted on equipment and pipelines within a certain range only through one detection unit, and therefore the safety guarantee cost is remarkably reduced while safety production is guaranteed.

Description

technical field [0001] The invention relates to an underwater caisson oil leakage detection device, belonging to the technical field of marine development and marine protection, in particular to the field of emergency disposal of underwater oil leakage. Background technique [0002] The subsea oil production system is integrated and installed in the caisson. With the progress of the production process, the equipment, pipes and valves of the subsea oil production system may leak. Therefore, it is necessary to monitor them in time to ensure that the sea surface platform can detect leakage problems in time. [0003] The oil production system in the caisson has a complex structure and occupies a large space. If the detection is carried out in a point-to-point manner, a lot of detection equipment will be required. For example, the pipeline leakage detection in the prior art requires the use of underwater robots, and a complete system is required for control and detection. , which...
